Is it safe to give a six-year-old a 10 mg melatonin because my mom gave her one without asking me

I’m really upset right now my daughter spent the weekend with my parents this past weekend and when my daughter got home she told me mommy I want more sleeping medicine. I immediately was like what are you talking about she said my mom gave me a sleeping medicine. So I asked my mom about it if she was a yeah when I was taking my stuff to go to sleep I took one of my melatonin gummy‘s so I asked her if she wanted one and it was crazy not even 10 minutes after giving it to her she knocked out cold it really work you should try them. No I know it’s just melatonin and I know a lot of friends that give melatonin to their children when they can’t sleep but it’s the fact that a she gave it to her without asking me and be she gave her so much. She gave her one of her whole 10 mg melatonin gummy‘s and I’ve always heard About people giving their kids like 3 mg ones and it scares me that she passed out so hard and so quickly after taking it. No I will say in my mom’s defense my daughter has not spent the night with them in years because my mom’s been moving around a lot and each time she moves to a new house my daughters scared to spend the night and I guess she just really wanted her to be able to spend the night But it still upsets me that she gave her medication without asking me
